A few days ago, several countries signed ACTA, the Anti-Counterfeiting Trade Agreement. As you are probably aware, ACTA was drafted up in secret, and is basically Obama/Biden's attempt to impose the US' draconian pro-big business/big content protection laws on the rest of the world ('sign it, or else'). The European Parliament still has to vote on it, and as such, Douwe Korff, professor of international law at the London Metropolitan University, and Ian Brown senior research fellow at the University of Oxford, performed a 90-page study, with a harsh conclusion: ACTA violates fundamental human rights.

Due process isn't a right, it is a procedural restriction on the government to prevent it from acting arbitrarily and in conflict with the law, so that is doesn't illegally infringe on actual rights. So in other words: you don't have a right to due process, you have rights and the government cannot infringe on those rights without first following the due process of law.

As far as I know, at least in the US, it is a right, inscribed in the Fifth Amendment to the US Constitution (the amendment being part of the "United States Bill of Rights"), which reads, in part:

"[No person shall] be deprived of life, liberty, or property, without due process of law".

Now of course I am not a constitutional lawyer, so I might be wrong. After all, all I do is read what the letters say in English, not Legalese...
